Usually, when I turn my car on my rpms jump up to about 1,500 rpms, and it stays there for a good minute.

If I put my car in Drive (automatic obviously), say instantly, my car gives a little jump and goes down to about 500-800 rpms. Now my tranny has been serviced recently and it shifts beautifully.

If I wait the minute, my car doesnt do the little jump. It will just shift nice and smooth.

Is this a problem or is it normal?

 

Its warming itself up

 

let the car idle until it sets to about 1000rpms and then shift and see if it still happens..could be just cold

 

^^^^^^^^mine does it in the cold

 

Yup, normal. Mine does that too.

 

perfectly normal, its just warming up and waiting for the engine to find a set idle, no prob
